I understand; it's a matter of culture and values. In my country, it's normal to have boyfriends or girlfriends from the age of 12 to 14, and for there to be a difference of up to 5 years. Although I don't agree with it because I know that emotional maturity isn't present at that age.
But in this case, we're talking about a couple where both are of legal age, and frankly, even though he's a student, being Kayden Jiwoo's disciple gives him more power in the relationship.

Dropped this awhile back because it felt like like the author was building up some weird romance between baby boy and lady boss and that made me feel icky - do they get together/ is that still an ongoing plot point ?
